大巷带式输送机的选型及其自动张进装置的设计
摘要
本次设计是关于矿用大巷带式输送机的选型及其自动张进装置的设计。带式输送机是连续运动的无端输送带输送货物的机械。它结构简单,造价低,运输距离长,而且有较高的生产效率。主要用于生产,采矿,冶金,煤炭,电站,港口,以及工业企业。随着工业科学技术的发展,带式输送机在工业生产中的重要性越来越大。本介绍了带式输送机的各部件的选型设计过程。根据给定的原始数据和初始参数,选择输送机类型,确定其布置形式,初定输送带和托辊及其间距;然后计算输送机系统的各种阻力以及所需的总功率,计算各部分的张力,再依据带式输送机各部件的选型计算标准,完成各个部件的选型。从而完成带式输送机的选型设计,同时要符合经济与安全的标准。并对皮带机的张紧装置进行了设计,画出了张紧装置装配图和液压系统原理图。张紧装置是保证带式输送机正常运转必不可少的重要部件。该介绍了带式输送机的自动张紧装置的设计过程,详细的介绍了各个液压元件的选取。自动张紧装置的设计是张紧装置的设计的一个重大变革。
